WASH BOWL.

SPECIFICATIONforming part of' Letters Patent No. 531,992, dated January1, 1895.

Application tiled .Tune 28, 1887. Serial No. 242,709. (No model.)

To di whom, it may concern.:

Be it known that I, ALLEN I. CREQUE, of New York, county of New York,and State of' New York, have invented an Improvement in Washbowls, ofwhich the followin g description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention relates to wash-bowls and has for one of its objects toimprove the construction of the same, whereby the outlet of the saidbowl may be rendered air or gas tight to prevent the admission of sewerand other gases into the house during the night. This feature of myinvention I accomplish by means ot a sealing device to be described,which is adapted to be inserted into the main outlet pipe below thepoint where the overliow pipe empties therein, the said sealing deviceiitting the said main outlet pipe gas and water tight so that gas isprevented from passing up into the bowl, the over-flow and main outletpipe above the said seal being preferably filled with water to renderthe obstruction to the passage of sewer gas absosutely sure, the saidwater being prevented from being siphoned out of' the said trap andpipes by the said seal.

My improved sealing device is adapted to be removed in the day time, aremovable strainer or sieve being then placed in the outlet pipe, thesaid trainer being removed when the sealing device is inserted therein.

illy improved sealing device may also be employed to remove any dirt,grease, dac., which may adhere to the inside of the outlet pipe, thesaid dirt, grease, dsc., after lapse of time putrifying and therebygiving rise to delete rious odors and gases which are unwholesome andunsanit-ary.

The particular features in which my invention consists will be pointedout in the claims at the end of' this specification.

Figure lis a vertical section of a wash bowl constructed in accordancewith my invention and provided with my improved sealing device, thelatter being shown in elevation; Fig. 2, a side view ot the bowl lookingtoward the right in Fig. 1 the over-flow pipe being omitted; Fig. 3, asection of Fig. 2 on line .ac-:0; Fig. 4, an enlarged detail of thesealing device removed from Fig. 1; Figs. 5, 6 and 7 details to bereferred to; Fig. 8, an under side view ot the portion of overflow pipewhich is fastened to the bowl; Fig. 9, a section of Fig. 8 on line -x,and Figs. 10 and ll, details to be referred to.

The bowl A, provided at its bottom, see Fig. 3, with a main outlet a,and at is sides with an over-flow passage a may be composed of porcelainor other material suoli as now commonly used. The outlet passage a iscontracted or made of smaller diameter for a poi'- tion of its length,to form a shoulder a2 to support a packing ring a3, see Fig. l,the saidpacking ring being shown in section as a right-angled triangle, thehypotenuse a* ot which forms a seat for a nozzle ai, which is extendedfrom inside the bowl A through the outlet passage a, and beyond theoutside of the said bowl.

The portion of the nozzle a projecting beyond the bowl A is screwthreaded as shown on its outside, to be engaged by a threaded ring ahaving a flange a7, a packing as being interposed between the said ringand the bowl A.

The nozzle ai receives within it one end Z), see Figs. 1 and 5, of apipe section b', having a flange h2, between which and the ring ai isanother packing ring h3, the pipe section h and packing ringl)3 beingsecured in position by a clamping device herein shown as a ring b4fastened to the clamping ring a6 by bolts b5 extended through the saidclamping rings and secured by nuts b, the said packing rendering thebowl water tight at its main outlet. The pipe section b is provided withan angular extension or branch bT united as shown by a wipe joint 138 toone end of an overlow pipe b9, the other end of which is united by aWipe joint blo to one end of the overflow section hm. See Figs. 1, 8 and9.

The over-flow section blz, see Figs. 8 and 9, has a flange c made to t ashoulder or lange c around the overflow passage a', a packing ring c2being interposed between the shoulder c and flange c, the said packingring and overflow section Z212 as shown being secured to the bowl A bybolts not shown, but which are inserted' through holes c3, see Fig. 8,in the ears c4 of the liange c, and through holes or openings cX in theflange c. See Fig. 2.

The pipe section h has connected to or forming part of it one end ot apipe as c5, see Fig. 1, whichis extended into an opening in TCO a cap c,a second opening in said cap having connected to it. a bent pipe c7, thesaid cap having an outlet which is closed by a threaded plug cs,.thepipes c5 c7 and cap c6 forming a trap of ordinary form and such as nowcommonly used in connection with wash bowls and sinks.

To prevent the passage ot sewer gas through the trap referred to andinto the room or closet in which the wash-bowl maybe located, I haveprovided a sealing device by which ythe pipe Zi or the pipec5 below thebranch D7 is rendered gas and water tight.

Thesealing device referred to, see Figs. l and 4, is herein shown ascomposed essentially of two rings or disks d, d', preferably of rubber,having a central hole through which is extended a foot daof a spindle orstem d3, the said rings or disks being separated by a washer d4 andbeing secured on the said foot, as shown, by a nut d5, a washer Z6 beingshown interposed between the said nut and the disk CZ. rEhe rings ordisks CZ, d', are preferably beveled at their edges or periphery inopposite directions. The spindle or stem d3 will preferably have upon ita collar C17, see Fig. lO, joined by radial ribs d8 to a ring dg, thelatter being designed to rest upon the upper end l) of the pipe sectionb to form with a pin d10 on the spindle d, a stop for the said spindlewhen the latter is in its elevated position, shown in Fig. l. The collard? has a groove or notch e through which the pin d10 may be passed tochange the position of the disks d, d', in the pipes b and c5.

As shown in Fig. l the spindle d3 and the attached disks d, d', are inthe position to be occupied by them at night time when it is desired toprevent the admission of sewer gas into the house, the pin d10 beingabove the collar all and the spindle turned so as to bring the said pinout of line with the groove or notch e, the said pin resting upon .thesaid collar and serving to support the said spindle and disks inelevated position.

The disks d, d', fit the pipe ZJ gas tight, so that any gas in the pipec5 is prevented from passing up above the said disks, and the said disksalso prevent the water either in the pipe b above the said disks or inthe cveriiow pipe or bowl A or in the trap below the said disks frombeing siphoned off or evaporated.

During the day-time, the sealing device is removed, the pin d10 beingplaced in the dotted line position shown in Fig. 1, and the spindle andattached disks and also the collar are removed by withdrawing the saidspindle by means of the handlef.

In the daytime an ordinarystrainerf', such as shown in Fig. 7, may beseated upon the end b of the pipe section b', it having a handle f2 ifdesired, by which it may be easily removed as shown in Fig. 5.

The outlet passage a may be closed, when it is desired to use the bowlin the day time, by a plug f3 fitted into the nozzle a5, and having aring]c4 by which it may be removed.

When desired the pipes b and c5 may be cleansed from dirt and grease byworking the spindle cl3 up and down in the said pipes, the disks d., d',removing the said dirt or grease adhering to the sides ofthe said pipes.

I prefer to employ a sealing` device composed of two disks but it isevident one disk may be dispensed with.y

l. A wash bowl, an outlet nozzle therein, an outlet pipe of uniformdiameter from the nozzle to the bend of the usual trap, and an over flowpipe opening into the outlet pipe below the bowl, combined with asealing and cleaning device, consisting of a suitable number of flexibledisks, and a spindle to which they are aftixethsaid spindle being ofsuiiicient length to be worked with its disks up and down the entirelength of the outlet pipe from the outlet nozzle to the trap and alsobeing freely removable at .pleasure together with its flexible disksfrom the pipe and bowl, substantially as described.

2. The bowl A, nozzle a5, packing a3 interposed between said nozzle andbowl, ring a, packing a8 interposed between the ring a@ and bowl A,clainping ring b4 and packing b3, combined with the pipe section b having aiange and an end l) to fit the nozzle, and with means to fasten the saidrings to-gether, substantially as described.

, 3. The bowl, the nozzle d5, and the independent pipe section b and thepipe c5, the interior of the pipe section b and the interior of the pipec5 being Hush to form a uniform continuous passage, combined with aremovable sealing device comprising a ring of elastic or yieldingmaterial anda spindle or stem d3, the said removable sealing devicebeing capable ot' effectively cleansing the outlet pipe, substantiallyas described.

et. The bowl, its nozzle provided with an ordinary plug-seat and adaptedto receive a removable strainer, an outlet pipe, and means to connect itwith the nozzle, the said outlet pipe being substantially straightand ofuniform diameter from the nozzle to the bend in the usual trap, andadapted to receive a cornbined sealing and cleaning device consisting ofa suitable number of disks and a spindle to which the disks are secured,substantially as and for the purpose described.

5. A wash bowl having an outlet pipe of uniform diameter, and anoverflow pipe connected to it, combined with a sealing device comprisinga disk or ring of flexible material and a spindle and a stopping device,the said sealing device and its stopping device being bodily removablefreely and at pleasure through the bowl, substantially as described.
